摘要

提出并分析了一种简单、低成本、鲁棒的“民主”(自主)电流共享电路。该电路根据并联模块的平均电流与单个模块的电流之间的差异，通过适当调整模块的参考电压来保持模块之间良好的电流共享。给出了实现理想的电流共享性能的设计指南，并在多个并联运行的DC/DC功率转换器模块上进行了验证。

A novel, low-cost implementation of "democratic" load-current sharing of paralleled converter modules

A simple, low-cost, and robust "democratic" (autonomous) current-sharing circuit is proposed and analyzed. The circuit maintains good current sharing among the modules by properly adjusting the voltage references of the modules based on the differences between the average current of the paralleled modules and the currents of the individual modules. Design guidelines for achieving a desired current-sharing performance are given and verified on a number of DC/DC power converter modules operating in parallel.<>
